5 is hollow and made elastic by means of.

longitudinal slits 13 as before, but the ohannel 11 is omitted and the upper end of the rod is solid and has'the handle 15 secured Communication betweenthe longitudinal air passage (formed by the hol,- loW lower end of the cooling rod) and the surrounding air is afford-ed in this case by apertures 17 openinginto the space between the cup 11 and the cooling rod'.

Figs. 3 and '4 show another construction according to which the cooling rod comextending through.

' tube and the cooling rod. 24 applied to theputerend rigidly to 'the prises two members 5a and 5b made in the shape ci cylinder segments, spaced to form .slits between their opposingedges and also forming a longitudinal passage or channel which at its upper end communicates with the surrounding air and at its lower end with the interior'l of the ianticathode tube 3. The upper' ends'of the members 5e, 5* are crossed and connected pivotally at 18 after the fashion of scissors, their extremities 19, 20 constitutingvhandles. To one of` these handles, 20, is pivoted` a transverse rod 22 an opening 21 in the other handle 19, and a' around the rod 22, tends t orce the handles 19, 20 apart and thus presses the rod members 5a, 5b firmly against the inner surface of the anticathode tube 3, thus insuring a good heat-exchange relation between such An annular cap of the nipple 12, serves as a guide vfor the cooling rod 5a, 5b. ln Fig. 5, semicircular extensions 26 and 2,7, pivotally connected at 25, are secured respectively, and across the loop formed by the said extensions is placed a rod 28 pivoted to one of the extensions, 26, and passing loosely through an opening extension 27. spring 29, coiled around sadod 28, pressesthe. members 5, 5b apart,

to secure the same action as described with reference toFigs 3 and at. course a `spring bow or loop may be substituted for the spring 29, rod 28 and the twopart bow formed by .the pivotally connected extensions 26,27.

' In Figs. 6 and 7 the.member 5c is made hollow angl provided at its outer end with lcooling medium 31.

permanently, is the same as in spring 23, coiled t o segmental members 5a and 5b 30' in the other` specification in the a cup like receptacle 5 adapted to receive a The other member 5d of the cooling rod has segmental cross section', as shown in Fig. 7, and is pivotally connected to thelateral arm 32 of the member 5c at 33. The outer end of the member 5* terminates in an arm 34, and the ends of the arms 32 and 34 are provided with handles 35 and 36 respectively. A spring 37, being coiled around the rod 38 pivoted to the arm 34: at 39, presses the arms 32 and 34 apart, so as to. bring the members 5c and 5d in close heat-exchange contact with the interior wall of the anticathode tube, and at the sume time 'td form between said members 5c, 5, a longitudinal air passage communicating with the interior of the anticathode tube 3' and with the outer air. vAfter the cooling medium 31 has absorbed heat to a sulicient degree, the cooling rod 5, 5? may be removednrom the anticathode tube in order to replace the heated medium contained in the member 5c and its receptacle 5 with fresh cooling medium. In' certain cases the member 5* of the device shown in Figs. 6 and 7, may likewise vbemade hollow and filled with a cooling ,medium While compression springs have been shown in Figs. 3, 5 and 6 at 23, 29 and 37 respectively, it will be' obvious that tension springs or other devices `may be used for theI same purpose. These modifications and others may be made without departing from.

the nature of my invention as -set, loitli ifr-` t'he appended claims.

Claim: i -1 l. A Rntgen tube rovided with an anticathode. ,anahticathode tube extending outwardly from the anticathode and open fst.

its outer end, and a cooling'rod adapted to be set removably within said anticuthode tube, said rod being tendency to expand in spring-like fashion so as to seeurea close heat-exchange contact bef tween the outer surface of the coolin rod and the inner surface tube.

2. A Rntgen tube cathode, an anticatho e tube extending out.- wardly from the anticathode and a cooling rod adapted to beset remova rovided with an anticonstructed with a of the anticlt ode ly Within s uid anticathode tube, said rod consisting, of a plurality y of ovably connected members, and means forf'forcing them engagement with the anticathode tube.
